Apple A5

The Apple A5 is a 32-bit system-on-a-chip designed by Apple Inc. and manufactured by Samsung[3][4] and is the successor to the Apple A4. The A5 commercially debuted with the release of Apple's iPad 2 tablet, and also powers the iPhone 4S, iPod Touch fifth generation, Apple TV third generation, and the iPad mini first generation. This is consistent with how Apple debuted the A4 chip: first in the original iPad, followed by the iPhone 4, and then the iPod Touch (fourth generation).[5] Apple claims that compared to its predecessor, the A4, the A5 CPU "can do twice the work" and the GPU has "up to nine times the graphics performance".[6]

The A5 consists of a dual-core ARM Cortex-A9 CPU[7] with NEON SIMD accelerator and a dual core PowerVR SGX543MP2 GPU.[2] Apple lists the A5 to be clocked at 1 GHz on the iPad 2's technical specifications page,[8] though it can dynamically adjust its frequency to save battery life.[9][7] The unit used in the iPhone 4S is clocked at approximately 800 MHz.[10] Apple has also included an image signal processor unit (ISP) that will do advanced image post-processing such as face detection, white balance and automatic image stabilization[11] and an "earSmart" unit from Audience for noise canceling.[12]

When the A5 was first released, it was estimated at that time to cost 75% more than the previous generation, with the difference expected to diminish as production increased.[13] As of August 2012, the A5 is manufactured at Samsung's Austin, Texas factory.[14] Samsung invested $3.6 billion in the Austin facility to produce chips such as processors, and nearly all of that facility's output is dedicated to Apple components.[15] Samsung has invested a further $4.2 billion at the Austin facility in order to transition to a 28 nm fabrication process by the second half of 2013.[14]

The A5 part model numbers are: S5L8940 (45 nm version), S5L8942 (32 nm version) and S5L8947 (32 nm, single core version).[16] A version of the A5 with a wider memory subsystem and four graphic cores is called Apple A5X and is found in the third generation iPad.

Apple A5 (S5L8940)

Apple uses the first version of the A5 chip in the iPhone 4S, and iPad 2.[17] The A5's manufacturing process is 45 nm and it has 122.2 mm2 of die area.[18] It is manufactured in a package on package (PoP) together with 512 MB[18] of dual-channel[1] LP-DDR2 DRAM.[19]

Apple A5r2 (S5L8942)

Apple used a second version of the A5 chip in the third generation Apple TV, announced on March 7, 2012,[20] as well as the iPod Touch fifth generation, the iPad mini, and the 32 nm revision of the iPad 2.[21] This chip is manufactured with a 32 nm fabrication process, with ID code S5L8942 and it has one core disabled in the Apple TV.[22] The new A5 measures nearly 41% smaller than first-generation A5, coming in at 69.6 mm2[22] and manufactured in a package on package (PoP) together with 512 MB LPDDR2 DRAM.[23][24]

Apple A5r3 (S5L8947)

In March 2013, Apple released an updated version of the third generation Apple TV (AppleTV3,2) containing a smaller, single CPU core and single GPU core version of the A5 processor.[25] Unlike the other A5 variants, this version of the A5 is not a package-on-package (PoP), having no stacked RAM.[23] The chip is very small, just 37.8 mm2,[23] but as the decrease in size is not due to a decrease in feature size (it is still on a 32 nm fabrication process), this indicates that this A5 revision is of a new design.[26] Markings tell that it's named APL7498, and in software, the chip is called S5L8947.[27][23]

ARM Cortex-A

The ARM Cortex-A is a group of 32-bit and 64-bit RISC ARM processor cores licensed by Arm Holdings. The cores are intended for application use. The group consists of 32-bit cores: ARM Cortex-A5, ARM Cortex-A7, ARM Cortex-A8, ARM Cortex-A9, ARM Cortex-A12, ARM Cortex-A15, ARM Cortex-A17 MPCore, and ARM Cortex-A32, and 64-bit cores: ARM Cortex-A35, ARM Cortex-A53, ARM Cortex-A55, ARM Cortex-A57, ARM Cortex-A72, ARM Cortex-A73, ARM Cortex-A75, and ARM Cortex-A76.

The 32-bit ARM Cortex-A cores, except for the Cortex-A32, implement the ARMv7-A profile of the ARMv7 architecture. The main distinguishing feature of the ARMv7-A profile, compared to the other two profiles, the ARMv7-R profile implemented by the ARM Cortex-R cores and the ARMv7-M profile implemented by most of the ARM Cortex-M cores, is that only the ARMv7-A profile includes a memory management unit (MMU). Many modern operating systems require a MMU to run.

The 64-bit ARM Cortex-A cores as well as the 32-bit ARM Cortex-A32 implement the ARMv8-A profile of the ARMv8 architecture.

ARM Cortex-A9

The ARM Cortex-A9 MPCore is a 32-bit processor core licensed by ARM Holdings implementing the ARMv7-A architecture. It is a multicore processor providing up to 4 cache-coherent cores.

Apple-designed processors

Apple Inc. has developed a range of "System on Chip" (SoC) as well as "System in Package" (SiP) processors for powering their mobile consumer devices and other tasks. To meet the stringent power and space constraints common to mobile devices, these chips combine a central processing unit (CPU) with other components into a single compact physical package. Johny Srouji is the executive in charge of Apple's silicon design.

Apple A4

The Apple A4 is a 32-bit package on package (PoP) system-on-a-chip (SoC) designed by Apple Inc. and manufactured by Samsung. It combines an ARM Cortex-A8 CPU with a PowerVR GPU, and emphasizes power efficiency. The chip commercially debuted with the release of Apple's iPad tablet; followed shortly by the iPhone 4 smartphone, the iPod Touch (4th generation), and the Apple TV (2nd generation). It was superseded by the Apple A5 processor used in the iPad 2 released the following year, which was then subsequently replaced by the Apple A5X processor in the iPad (3rd generation).

Apple A5X

The Apple A5X is a 32-bit system-on-a-chip (SoC) designed by Apple Inc., introduced at the launch of the third generation iPad on March 7, 2012. It is a high performance variant of the Apple A5; Apple claims it has twice the graphics performance of the A5. It was superseded in the iPhone 5 and 5C by the A6 chip and the fourth generation iPad by the A6X chip.

Apple A6

The Apple A6 is a 32-bit package on package (PoP) system on a chip (SoC) designed by Apple Inc. that was introduced on September 12, 2012 at the launch of the iPhone 5. Apple states that it is up to twice as fast and has up to twice the graphics power compared with its predecessor, the Apple A5.

Apple TV

Apple TV is a digital media player and microconsole developed and sold by Apple Inc. It is a small network appliance and entertainment device that can receive digital data such as music or video from specific sources and stream it to a television or other video display.

Apple TV is an HDMI-compliant source device. To use it for viewing, it has to be connected to an enhanced-definition or high-definition widescreen television via an HDMI cable. The device has no integrated controls and can only be controlled externally, either by an Apple Remote or Siri Remote control device (with which it is sold) using its infrared/Bluetooth capability, by the Apple TV Remote app (downloadable from App Store) on iOS devices, such as the iPhone, iPod Touch, iPad, and Apple Watch, using its Wi-Fi capability, or by some third-party infrared remotes.Its Wi-Fi capability is also used to receive digital content from various iOS apps using AirPlay or directly from the iTunes Store, which is then streamed to the TV. It also plays digital content from the iTunes Store, Netflix, Stan, Foxtel Now, Hulu, Now TV (UK only), SlingTV, PlayStation Vue, Amazon Prime Video, DirecTV, YouTube, Red Bull TV, and Vevo along with HBO Now, Showtime Anytime, Starz, and the TV Everywhere portals of several cable and broadcast networks, and the video subscription portals of all of the four major North American sports leagues: NFL TV app,, NBA League Pass, and It plays content from any macOS or Windows computer running iTunes. Apple began to promote the Live Tune-In feature that allows the viewer to ask Siri to tune to live streams of CBS, ESPN, and Disney XD among many others that support Live Tune-In.

According to observers, Apple's March 2019 special event highlighted the company's reorientation of its focus away from the Apple TV hardware, which has lagged competitors with only 13% of U.S. connected TV market share, and apps on the set-top box, and instead turn toward higher revenue Apple-distributed video streaming that will be available even through competitors' devices, via the company's upcoming Apple TV+ original content service and Apple TV Channels a la carte premium video on demand subscription aggregating service.

iPad ( EYE-pad) is a line of tablet computers designed, developed and marketed by Apple Inc., which run the iOS mobile operating system. The first iPad was released on April 3, 2010; the most recent iPad models are the iPad (2018), released on March 27, 2018; the fifth-generation iPad mini, released on March 18, 2019; the third-generation iPad Air, released on March 18, 2019; and the 11-inch (280 mm) and third-generation 12.9-inch (330 mm) iPad Pro, released on November 7, 2018.

As of May 2017, Apple has sold more than 360 million iPads, though sales peaked in 2013. It is the most popular tablet computer by sales as of the second quarter of 2018.The user interface is built around the device's multi-touch screen, including a virtual keyboard. All iPads can connect via Wi-Fi; some models also have cellular connectivity. iPads can shoot video, take photos, play music, and perform Internet functions such as web-browsing and emailing. Other functions – games, reference, GPS navigation, social networking, etc. – can be enabled by downloading and installing apps. As of March 2016, the App Store has more than million apps for the iPad by Apple and third parties.

There have been eight versions of the iPad. The first generation established design precedents, some of which have persisted through all models. The 2nd-generation iPad (iPad 2) introduced a new thinner design, a dual-core Apple A5 processor, and VGA front-facing and 720p rear-facing cameras designed for FaceTime video calling. The third generation added a Retina Display, the new Apple A5X processor with a quad-core graphics processor, a 5-megapixel camera, HD 1080p video recording, voice dictation, and 4G (LTE). The fourth generation added the Apple A6X processor and replaced the 30-pin connector with an all-digital Lightning connector. The iPad Air added the Apple A7 processor and the Apple M7 motion coprocessor, and reduced the thickness for the first time since the iPad 2. The iPad Air 2 added the Apple A8X processor, the Apple M8 motion coprocessor, an 8-megapixel camera, and the Touch ID fingerprint sensor; and further reduced the thickness. The iPad introduced in 2017 added the Apple A9 processor, while sacrificing some of the improvements the iPad Air 2 introduced in exchange for a lower launch price.

There have been five versions of the iPad Mini, all of which have a screen size of 7.9 inches (20 cm). The first generation has similar internal specifications to the iPad 2 but uses the Lightning connector instead. The iPad Mini 2 added the Retina Display, the Apple A7 processor, and the Apple M7 motion coprocessor, closely matching the internal specifications of the iPad Air. The iPad Mini 3 added the Touch ID fingerprint sensor. The iPad Mini 4 features the Apple A8 and the Apple M8 motion coprocessor. The 5th generation features the Apple A12 SoC.

There have been three generations of the iPad Pro. The first generation came with 9.7" and 12.9" screen sizes, while the second came with 10.5" and 12.9" sizes, and the third with 11" and 12.9" sizes. The iPad Pros have unique features such as the Smart Connector, which are exclusive to this series of iPads.

IPad 2

The iPad 2 is a tablet designed, developed and marketed by Apple Inc. Compared to the first iPad, as the second model in the iPad line it gained a faster dual core A5 processor, a lighter build structure, and was the first iPad to feature VGA front-facing and 720p rear-facing cameras designed for FaceTime video calling.

The device was available initially with three storage sizes – 16, 32, and 64GB – and two varying connectivity options – Wi-Fi only or Wi-Fi and cellular. Each variation of the device is available with either a black or white front glass panel. However, upon the release of the 3rd generation iPad in March 2012, only the 16GB variation with two connectivity options and two front color options remained available.

The product became available in March through May 2011.

The device received mixed to positive reception from various blogs and publications. Although it was praised for its hardware improvement, such as the new Apple A5 chip, the software restriction on the iPad 2 and iOS in general drew criticism from various technology commentators. The device sold well in its first month of sales with 2.4–2.6 million units sold and 11.12 million units were sold in the third quarter of 2011.A popular product, with a lower screen resolution and performance than the two Retina models that followed it but a lighter build and longer battery life, it remained in the Apple line-up as an entry-level iPad model for three years until March 2014, latterly with a silent upgrade to a die-shrunk version of the A5 processor. Its basic design formed the core of the first iPad mini, which had the same screen pixel count and similar features at a smaller size.

The iPad 2 was the only device to receive six major versions of iOS, from 4 to 9; until iOS 12 was released for the iPhone 5S, iPad Air and iPad Mini 2.

IPad Mini

The iPad Mini family (branded and marketed as iPad mini) is a line of mini tablet computers designed, developed, and marketed by Apple Inc. It is a sub-series of the iPad line of tablets, with a reduced screen size of 7.9 inches, in contrast to the standard 9.7 inches. The first generation iPad Mini was announced on October 23, 2012, and was released on November 2, 2012, in nearly all of Apple's markets. It features similar internal specifications to the iPad 2, including its display resolution.

The second generation iPad Mini, with a faster processor and a Retina Display, was announced on October 22, 2013 and released on November 12, 2013. The third generation iPad Mini was announced on October 16, 2014 and was released on October 22, 2014; it features the same external hardware as the Mini 2 and the addition of a Touch ID fingerprint sensor compatible with Apple Pay. On September 9, 2015, Apple released the iPad Mini 4. On March 18, 2019, Apple released the 5th generation iPad Mini.

IPad Mini (1st generation)

The first-generation iPad Mini (stylized and marketed as iPad mini) is a mini tablet computer designed, developed, and marketed by Apple Inc. It was announced on October 23, 2012, as the fourth major product in the iPad line and the first of the iPad Mini line, which features a reduced screen size of 7.9 inches (20 cm), in contrast to the standard 9.7 inches (25 cm). It features similar internal specifications to the iPad 2, including its display resolution.

The first generation iPad Mini received positive reviews, with reviewers praising the device's size, design, and availability of applications, while criticizing its use of a proprietary power connector, its lack of expandable storage, and the lack of Retina display.

IPhone 4S

The iPhone 4S (retroactively stylized with a lowercase 's' as iPhone 4s as of September 2013) is a smartphone that was designed and marketed by Apple Inc. It is the fifth generation of the iPhone, succeeding the iPhone 4 and preceding the iPhone 5. Announced on October 4, 2011 at Apple's Cupertino campus, its media coverage was accompanied by news of the death of former Apple CEO and co-founder Steve Jobs on the following day.

Orders could be placed on October 7, 2011 and mainstream availability in retail stores began on October 14, 2011 in the United States, Australia, Canada, the United Kingdom, France, Germany, and Japan. Sales peaked over its predecessor with more than a million sales in the first twenty-four hours of order availability and more than four million sales in the first four days of retail availability. Further worldwide rollout, including 22 additional countries on October 28, came over the next several months.This iPhone was named "4S" where "S" stood for Siri an iPhone 4S-exclusive intelligent personal assistant that was later included in future generations of mobile Apple products. Retaining most of the external design of the iPhone 4, the 4S hosted major internal upgrades, including an upgrade to the Apple A5 chipset, and an 8-megapixel camera with 1080p video recording. It debuted with iOS 5, the fifth major version of iOS, Apple's mobile operating system, that introduced features including iCloud, iMessage, Notification Center, Reminders, and Twitter integration.

Reception to the iPhone 4S was generally favorable. Reviewers noted Siri, the new camera, and processing speeds as significant advantages over the prior model. It was succeeded by the iPhone 5 as Apple's flagship phone on September 12, 2012. The iPhone 4S remained on sale, albeit being sold with reduced storage (from 16/32/64 GB down to 8 GB). The 4S was officially discontinued on September 9, 2014 following the announcement of the iPhone 6, although production did continue for developing markets until February 17, 2016. During the course of its lifetime, the iPhone 4S was the best-selling iPhone ever produced and it is the first iPhone to support five major versions of iOS: iOS 5, iOS 6, iOS 7, iOS 8, and iOS 9 (the iPad 2 was supported from iOS 4 to iOS 9). The 4S is also the last iPhone to have the original 30 pin connector as the succeeding iPhone 5 replaced it with the all digital Lightning Connector.

IPod Touch

The iPod Touch (stylized and marketed as iPod touch) is a brand of iOS-based all-purpose mobile devices designed and marketed by Apple Inc. with a touchscreen-controlled user interface. It connects to the Internet only through Wi-Fi base stations, does not use cellular network data, and is therefore not a smartphone. Similarly to an iPhone, it can be used as a music player, digital camera, web browser, note-logger, and handheld gaming device. As of May 2013, 100 million iPod Touch units had been sold since 2007.iPod Touch models are sold by storage space and color, with all models of the same generation typically offering otherwise identical features, processors, and performance, in addition to available operating system upgrades; an exception was the fifth generation, as the low-end (16 GB) model was initially sold without a rear-facing camera. The current iPod touch is the sixth-generation model, released on July 15, 2015.

The iPod Touch is currently the only product in Apple's iPod product line, following the discontinuation of the iPod Nano and iPod Shuffle on July 27, 2017. Following the discontinuation, Apple revised the storage and pricing for the iPod Touch with 32 and 128 GB of storage.

IPod Touch (5th generation)

The fifth-generation iPod Touch (stylized and marketed as the iPod touch, and colloquially known as the iPod Touch 5G or iPod Touch 5) was unveiled at Apple's media event alongside the iPhone 5 on September 12, 2012, and was released on October 11, 2012. An all-purpose pocket computer designed and marketed by Apple Inc. with a touchscreen-based user interface, it succeeded the 4th-generation iPod Touch. It is compatible with up to iOS 9.3.5, which was released on August 25, 2016.

Like the iPhone 5, the fifth-generation iPod Touch is a slimmer, lighter model that introduces a higher-resolution, 4-inch screen to the series with 16:9 widescreen aspect ratio. Other improvements include support for recording 1080p video and panoramic still photos via the rear camera, an LED flash, Apple's A5 chip (the same chip used in the iPad Mini (1st generation), iPad 2, and iPhone 4S) and support for Apple's Siri.

Additionally, unlike its predecessors, the iPod Touch was made available in space grey, silver, pink, yellow, blue, and Product Red.The device was initially only sold in 32 GB and 64 GB models. The first 16 GB model, introduced on May 30, 2013, was only available in one color and lacks the rear iSight camera and the iPod Touch Loop that is included in the 32 GB models. On June 26, 2014, it was replaced with a new 16 GB model that no longer omits the rear camera and full range of color options. The pricing for the iPod Touch had also changed. The 16 GB model is $199 instead of $229, the 32 GB model is $249 instead of $299, and the 64 GB model is $299 instead of $399.The iPod Touch (5th generation) was officially discontinued by Apple on July 15, 2015, with the release of its successor, the iPod Touch (6th generation). However, Apple still continues to sell refurbished models.
